Type of operation
Keep the heating unit pressure indicated on the display between 0.08 and 0.14
MPa (0.8 and 1.4 bar).
Periodically check the water pressure indicated on the display when coffee is being
dispensed: check the pressure indicated on the gauge, which must be in the range
of 0.8 to 0.9 MPa (8 and 9 bar).
Check the condition of the filters. Check for any damage on the edge of the filters
and check whether any coffee grounds settle in the coffee cup, and replace the
filters and/or filter holders, as required.
Check the ground coffee dose (between 6 and 7 grams per time) and check the
degree of grinding. Grinders must always have sharp cutting edges. Too much pow-
der in the grounds is an indication that the coffee is deteriorating. We recommend
calling out the Technician to replace the flat burrs after every 400/500 kg of coffee,
or after every 800/900 kg for conical burrs.
Replace the water filter cartridge or regenerate the water softener as often as speci-
fied by the manufacturer.
We recommend calling out the Technician at least once every three months to
replace the water in the heating unit.
